Thank you all for your investigations, advices, and tips! Yesterday I only had a little time. I just wanted to book cinema tickets quickly, and that was more of an odyssey on my old computer. Maybe, it was my own stupidity, I could have used my Android tablet directly. BTW, the movie "Top Gun - Maverick" was simply great! At home again, I have opened the problematic website www.uci-kinowelt.de in Serpent 52 (2022-09-10), and it works perfectly with a very fast and successful security check for my slow computer without any annoying captcha. That surprised me. Next, I opened it with a new profile in New Moon 28 (2022-09-10), and suddenly, what can I say, it works there too. Thanks @anton12 for your confirmation! In both cases, palefill 1.20 was installed. I still have to investigate why the security check cannot be completed successfully in my main profile of NM 28. Unfortunately, the 360Chrome browsers were no help in this case. I can say one thing with all clarity: I abysmally hate these sites with a so-called security check. Cheers, AstroSkipper And, one other thing is also very clear. The failure of the security check in my case is definitely not caused by an underperforming computer. And the browsers New Moon 28 and Serpent 52 have the most recent TLS 1.3 protocol and their current cipher suites. So the connection must be secure. The question must therefore be: What is actually checked during this so-called security check performed by Cloudflare? PS: The website www.uci-kinowelt.de and above all its login page works in Mypal 68 too like a charm without any significant delay or any captcha.

AstroSkipper Posted September 12, 2022 Share Posted September 12, 2022 (edited) So, as I suspected, one of my extensions in my main profile is preventing CF's security check of my internet connection from completing successfully. After disabling almost half of my extensions, it worked. Here is a screenshot from the UCI login page: I assume a captcha will only appear in the cases the visitor comes from a foreign country or the connection is actually secure but something went wrong and a captcha is given as an alternative to be sure it's not a bot after all. Just an idea! Anyway, which extension was the culprit now becomes a task for Sherlock Holmes.

Use the "divide-by-two" method... Say your dirty profile has 42 extensions installed in total 1. Disable the first 21 of them, then restart browser 2. Check for the existence of a bug (in this case, "CF-security-check" not completing) 3. If the bug is present, it's caused by one (or more) of the remaining enabled 21 extensions 4. If the bug is not present, then it's caused by one (or more) of the disabled 21 extensions By using this procedure for each "half" subset of extensions, adjusting accordingly for subsets with an odd number of extensions, you can hopefully arrive soon to the culprit one... The "(or more)" is for rarer circumstances, where a bug is caused by the interaction of two (or more) extensions, as opposed to one only... Worst case scenario: Some extension(s) will continue to interfere even when disabled; I hope yours is not such a case...

A nice and efficient algorithm! Truth be told, I already knew it, but thank you anyway, sometimes one does deviate from the perfect, theoretical construct. Unfortunately, I'm afraid that more than one extension is problematic. I am in the process of cleaning up my profile from several errors. Of course, I could simply create a new one, but if the same problems come up again, it will all have been for nothing. Besides, I have made and changed so many settings in this profile that it simply has to be saved. Frankly, I really want to know which extensions are causing problems. And, I've already found something. Edited September 13, 2022 by AstroSkipper Link to comment Share on other sites More sharing options...

With Serpent version 2022-09-10, unfortunately, it just opens to me a new dialog box, asking what to do with the file, rather than playing it inside the browser.

In my installations of New Moon 28 and Serpent 52, both most recent of 2022-09-10, your test file can only be played by the plugin VLC Web Plugin 3.0.3.0 which was automatically installed by VLC Media Player. I opened your mp4 test file via the file menu. Without the VLC Web Plugin, it won't play in my installations. Here is a screenshot when playing it with this plugin: Maybe, I missed something to play it natively in these browsers. This would be a good question for our experts. Truth be told, I rarely play videos in my browsers due to an underperforming computer. In most cases, I use an external media player like VLC for a better performance. BTW, I checked my about:config entries, and, as far as I can see, all necessary settings to play such videos have been done.

I know, but I mean, in Serpent 52 (not in New Moon 28), did you get a "What should do Serpent do with this file?" dialog box, or nothing happened? All what I did to have this happening, was: File --> Open File, locate the sample mp4 file, and it gave me the "What should do Serpent do with this file?" dialog box. The same happened when I dragged and dropped the file to Serpent. Link to comment Share on other sites More sharing options...

I have also completely removed all traces, settings, and remnants of old, uninstalled extensions. The extension which caused the issue on the UCI login page has been identified. And the winner is: RightToClick 2.9.6. The number of extensions has been reduced from 70 to 50. And yes, I know there are still too many, but I am a fan of extensions and use them all. I have upgraded every missing and useful feature. One of the reasons why New Moon 28 is my main browser. Now, New Moon 28 works like a charme with this profile. Thanks all for your help and tips!
